There's a difference? 
Haha, are you 13 at this moment perhaps?

Yeah, for in case you really didn't know: software are all the programs on you computer. So that means Msn, all of your games, so also sims and even your operating system, like windows, linux or mac.
The hardware is everything that you actually can touch. Your mouse, monitor, keyboard, webcam and microphone, if you have are all hardware. Printers and scanners are also concidered hardware.
A simple way to remember this: software is everything you can install or is installed on your computer. The hardware is everything that is not.
If you have further questions you better can mail me them as it will be too much offtopic to conversate them here in this topic.
